📐 A4 exact dimensions: 210 × 297 mm (8.3 × 11.7 in) | Area: 0.0625 m²
Formula: Pixels = (size in inches) × DPI
At 300 DPI, A4 = 2480 × 3508 pixels — the most common resolution for professional printing.

🧮 Conversion formula
Width (px) = 210 mm × (DPI ÷ 25.4) · Height (px) = 297 mm × (DPI ÷ 25.4)
1 inch = 25.4 mm. Multiply the size in inches by DPI to get pixels.

📏 What is A4 Paper Size?

A4 is the most common paper size worldwide, used in offices, schools, and homes. Its dimensions are 210 × 297 mm (8.3 × 11.7 inches), with an area of 0.0625 m². A4 is the standard for letters, forms, reports, and everyday printing. It's the foundation of the ISO 216 A-series and the reference size for all other A-series paper sizes.

📱 A4 Pixel Dimensions

The pixel dimensions of A4 depend on the resolution (DPI/PPI). Here are the most common A4 pixel sizes:

72 PPI (Web/Screen): 595 × 842 pixels
96 PPI (Standard Screen): 794 × 1123 pixels
150 DPI (Low Print): 1240 × 1754 pixels
300 DPI (Professional Print): 2480 × 3508 pixels
600 DPI (High Quality): 4961 × 7016 pixels
1200 DPI (Ultra High): 9921 × 14031 pixels

For professional printing, 300 DPI is the industry standard, giving you 2480 × 3508 pixels — a total of approximately 8.7 megapixels.

🧮 The Math: How to Convert A4 to Pixels

The conversion from A4 to pixels is straightforward. First, convert the A4 dimensions from millimeters to inches, then multiply by the DPI/PPI.

Width in inches: 210 mm ÷ 25.4 = 8.27 in
Height in inches: 297 mm ÷ 25.4 = 11.69 in
Pixels: (size in inches) × DPI

Formula: Width (px) = 210 × (DPI ÷ 25.4) · Height (px) = 297 × (DPI ÷ 25.4)

For example, at 300 DPI: Width = 210 × (300 ÷ 25.4) = 2480 px, Height = 297 × (300 ÷ 25.4) = 3508 px.

💡 Professional Tips for A4 to Pixels

🎯 Choose the Right Resolution

For professional printing, always use 300 DPI. For web and screen use, 72-96 PPI is sufficient. For large format prints, 150-200 DPI is acceptable.

📐 Vector vs. Raster

For A4 designs, use vector graphics (logos, text) whenever possible. They scale infinitely without losing quality. Raster images (photos) should be high-resolution (300 DPI at final size).

💾 File Size Management

At 300 DPI, A4 produces an 8.7 MP image. This creates manageable file sizes. For editing, use professional software that handles images efficiently. Consider using TIFF or PSD formats for editing and JPEG for final output.

🖨️ Printer Compatibility

A4 fits on standard office printers. Always check your printer's maximum resolution and supported file formats before sending files.
